C Specification

The VkVideoDecodeH264SessionCreateInfoEXT structure is defined as:

// Provided by VK_EXT_video_decode_h264
typedef struct VkVideoDecodeH264SessionCreateInfoEXT {
    VkStructureType                    sType;
    const void*                        pNext;
    VkVideoDecodeH264CreateFlagsEXT    flags;
    const VkExtensionProperties*       pStdExtensionVersion;
} VkVideoDecodeH264SessionCreateInfoEXT;


A VkVideoDecodeH264SessionCreateInfoEXT structure can be chained to VkVideoSessionCreateInfoKHR when the function vkCreateVideoSessionKHR is called to create a video session for H.264 decode.


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is reserved for future use.

  • pStdExtensionVersion is a pointer to a VkExtensionProperties structure specifying the H.264 codec extensions defined in StdVideoH264Extensions.

Valid Usage (Implicit)
  • VUID-VkVideoDecodeH264SessionCreateInfoEXT-sType-sType

  • VUID-VkVideoDecodeH264SessionCreateInfoEXT-flags-zerobitmask
    flags must be 0

  • VUID-VkVideoDecodeH264SessionCreateInfoEXT-pStdExtensionVersion-parameter
    pStdExtensionVersion must be a valid pointer to a valid VkExtensionProperties structure
